I have to prove that a binary system of stars of equal mass, temp, etc. is brighter by a magnitude of 3/4 than a single star of equal mass, temp, etc.(adsbygoogle = window.adsbygoogle || []).push({});

I've been trying to work it out with (m1-m2)=-2.5log(f1/f2)

Might anyone be able to tell me if I am even on the right track?
